[0002] At present, in the prior art, bicycle taillights usually only have basic lighting functions, and lack anti-theft and alarm functions. Since bicycle taillights are easily stolen or disassembled, there is a lack of effective safety measures when the bicycle is parked. In addition, when riding at night, the removal or damage of the bicycle taillight may also cause safety hazards. Therefore, it is necessary to provide a bicycle taillight with anti-disassembly alarm function to solve the shortcomings of existing bicycle taillights in terms of safety. Summary of the invention

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0022] like Figure 1 and Figure 2 As shown, a bicycle taillight with anti-disassembly alarm function provided according to the present invention comprises: a lamp body 1, a mounting bracket 2 and a battery module, and also comprises: a Hall sensor 3, a magnet 4, a control module 5 and a communication module 6;

[0023] The lamp body 1 is relatively mounted on the mounting bracket 2, the Hall sensor 3 is mounted on the lamp body 1, and the magnet 4 is embedded in the mounting bracket 2;

[0024] The battery module and the communication module 6 are installed in the lamp body 1 . The battery module supplies power to the lamp body 1 , the Hall sensor 3 , the control module 5 and the communication module 6 . The Hall sensor 3 and the communication module 6 are connected to the control module 5 , respectively.

[0025] In this embodiment, a Hall sensor 3 is installed in the lamp body 1 to cooperate with the magnet 4 embedded in the mounting bracket 2 to perform magnetic field detection. When the magnetic field of the magnet 4 cannot be detected after the lamp body 1 is removed from the mounting bracket 2, an alarm message is sent to the device management platform through the communication module 6 to promptly remind a specific user, thereby achieving a timely alarm when the bicycle tail light is disassembled, thereby effectively improving the safety of the use of the bicycle tail light.

[0026] In the above embodiment, preferably, when the lamp body 1 is installed on the mounting bracket 2, the Hall sensor 3 can detect the response magnetic field of the magnet 4 in the mounting bracket 2, and after the lamp body 1 is removed from the mounting bracket 2, the Hall sensor 3 cannot detect the response magnetic field of the magnet 4.

[0027] Specifically, by pre-designing the structures of the lamp body 1 where the Hall sensor 3 is located and the mounting bracket 2 where the magnet 4 is located, when the lamp body 1 is installed in cooperation with the mounting bracket 2, the Hall sensor 3 can detect the magnetic field of the magnet 4. Once the lamp body 1 is removed from the mounting bracket 2, the Hall sensor 3 can detect the magnetic field of the magnet 4 because the magnet 4 is far away, making the magnetic field it detects weaker than the preset magnetic field strength or unable to detect the magnetic field of the magnet 4, thereby realizing the detection of the action of the lamp body 1 being removed.

[0028] In the above embodiment, preferably, the magnet 4 is embedded in the mounting bracket 2 by injection molding. Further, the magnet 4 is preferably embedded by injection molding on the side of the mounting bracket 2 that contacts the lamp body 1, and the Hall sensor 3 is preferably installed on the side of the lamp body 1 that contacts the mounting bracket 2, that is, when the lamp body 1 is installed on the mounting bracket 2, the Hall sensor 3 and the magnet 4 are in the closest position.

[0029] like Figure 3 As shown, in the above embodiment, preferably, when the Hall sensor 3 changes from being able to detect the response magnetic field of the magnet 4 to being unable to detect the response magnetic field of the magnet 4, the communication module 6 can send an alarm message to the corresponding device management platform under the control of the control module 5.

[0030] In the above embodiment, preferably, when the Hall sensor 3 changes from being unable to detect the response magnetic field of the magnet 4 to being able to detect the response magnetic field of the magnet 4, the communication module 6 can send an alarm release message to the corresponding device management platform under the control of the control module 5.

[0031] In this embodiment, the Hall sensor 3 adopts a unipolar switch type Hall position sensor, and its circuit can be designed and processed using CMOS process technology, and is composed of a voltage stabilizing unit, a Hall sensor 3 with a dynamic deviation compensation system, a small signal amplifier, a Schmitt trigger and an open-drain output drive unit to form a magnetic sensor integrated circuit. The input control signal is the magnetic induction intensity, and the output is a switch type digital voltage signal.

[0032] like Figure 4 As shown in the figure, when there is no magnetic field control, the output tube of the sensor circuit will be turned off and the output will be high level; when the magnetic field strength B is greater than the working point (B OP ), the output switch tube will be turned on and the output will be low level; the output state will be maintained until the magnetic field strength B is lower than the release point (B RP ), the output switch tube is turned off and the output returns to a high level. When the magnet 4 approaches the Hall sensor 3 chip, the magnetic field generated is greater than B OP , when magnet 4 is far away, the magnetic field strength is lower than B RP These two situations cause the Hall sensor 3 chip to output a low level and a high level respectively.

[0033] The control module 5 detects whether the lamp body 1 is removed according to the low level and high level output by the Hall sensor 3 .

[0034] In the above embodiment, preferably, the communication module 6 adopts a Bluetooth BLE module, a cellular cat.1 communication module and a SIM card module, wherein the Bluetooth BLE radio frequency communication module can be integrated into the MCU microcontroller and integrated in the form of a SOC chip. At the same time, the Bluetooth BLE program also runs on the MCU microcontroller of the SOC chip.

[0035] In addition, during the cellular communication process, the cellular Cat.1 communication module is combined with the SIM card module. One cellular Cat.1 communication module cooperates with one SIM card module. A SIM card is inserted into the SIM card module to complete the communication interaction between the communication module 6 and the background device management server.

[0036] In the above implementation, preferably, the control module 5 adopts a single-chip microcomputer MCU, and is connected to the Hall sensor 3 and the communication module 6 through interfaces respectively.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
